GATE.

SPECIFICATION forming part of Letters Patent No. 407,951, dated July 30, 1889.

Application filed lvfarch 19, 1889- Serial No. 303,922. (No model.)

To all whom itmay concern:

Be it known that l, \VILLIAM L. I'IAAS, a citizen of the United States, residing at Charles City, in the county ,of Floyd and State of Iowa, have invented certain new and useful Improvements in Gates, of which the following .is a specification, reference being had therein to the accompanying drawings, in which Figure 1 represents a side elevation of my improved gate in a lowered position; Fig. 2, a view of the elevating devices, the gate be ing removed to better show them and they being in an elevated position. Fig. 3 is a detail, partly in sect-ion, of a portion of the elevating mechanism; Fig. 4, a horizontal section of the rearbattens, showing myiinproved eyebolt; and Fig. 5, a detail view of one of the serrated or roughened pintles.

The invention has essentially for its object the production of an extremely simple, durable, and practical arrangement for positively and readily adjusting a swinging gate in a vertical direction either for the purpose of compensating for sagging or of elevating it to avoid accumulations of snow, &c., or for any other purpose, as will more fully hereinafter appear.

The invention consists in certain novel features of construction and arrangement, that will be fully hereinafter described, and particularly pointed out in the claims appended.

Referring to the accompanying drawings by letters, A A represent, respectively, the supporting and latch posts, and B the gate proper, which is constructed, essentially, in this instance of the end battens C C, the center beam D,and the wires E, although it may be constructed in any other suitable manner and be provided with any suitable latch.

F F represent crank-arms 0r supports journaled in the supporting-post, the horizontal screw-threaded portions of these arms passing entirely through the said post, and

provided with thumb-nuts G G, which serve to hold the arms in any desired position, washers G G being interposed between these nuts and the face of the post A, as shown in Fig. 1. The horizontal portions of these arms are provided with shoulders a a, which abut against the face of the post when the thumb-nuts G are tightened, and serve to hold the arms steady and prevent undue vibration of the same. The swinging portions 1) b of the arms F are provided at their ends k with horizontal eyes or journals 0, through which pass the horizontal bolts (1, which clamp the tubular portions e of the pintles firmly to the outer ends of the said horizontal eyes 0. The adjacent faces of the parts 0 and e are provided with radial serrations to prevent the parts turning when once adjusted, as shown in Fig. 5. i

The horizontal bolts d have clamped upon them by means of nuts f f on their ends independent spacing-sleeves g g, these sleeves surrounding the portions of the bolts between the inner ends of the eyes 0 and the aforesaid nuts f f, washers f f being interposed between the latter and the spacing-sleeves.

Connecting the two spacing-sleeves g g upon the bolts is a vertical bar I, this bar being provided with holes near its ends for the free passage of the sleeves. By means of the spacing-sleeves it will be observed that the nuts on the ends of the bolts may be tightened to any degree without in the least binding the connecting-bar, which must work loose and free. By means of this connectingbar the crank-arms will be caused to move in perfect unison when the gate is adjusted either up or down.

The gate is hung upon the vertical pintles e e by means of eyebolts J J, clamped adjustably between the inner battens of the gate by means of nuts h 71, tapped on their ends, washers h h being interposed between the nuts and battens, as shown. These eyebolts are each constructed with a tapering body portion 76, which is adapted to fit between the battens and brace the same. They are also provided with oppositely-projecting shoulders 7c, which abut against the edges of the battens when the nuts are tightened and serve to clamp the same firmly. The body portions 74; of the eyebolts are formed with slots to render them light and strong.

\Vhen it is desired to adjust the gate, the nuts G and f are loosened sufficiently and the arms F F rotated the proper distance in their bearings in the post A, the pintlesleeves 6 being also rotated so as to keep the pintles e in an upright position, as clearly shown by dotted lines in Fig. 2. hen the supported thereby and carrying eyes at their ends, pintles bolted to these eyes, the adjacent faces of the pintles and eyes being serrated to prevent turning and a gate hung upon the said pintles.

3. The combination of a post, crank-arms supported by the said post and provided with eyes 0 c,pint1es, bolts for securing the pintles to the eyes 0, spacing-sleeves on these bolts, nuts for clamping the spacing-sleeves, and a connecting-bar.

In testimony whereof I affix my signature in presence of two Witn esses.-

WILLIAM L. HAAS.
